well I would like to thank Ryan for stepping up and helping me with this engine. 387ci just came off the dyno 612hp at 6600 and 538 at 5200 . Over all I am very happy this is a street engine with a small roller cam which may never see a 1/4 track. Thanks Ryan
After looking over the Dyno sheet this thing makes killer torque from 4500 to 6500 rpms makes no less than 500 ft lbs
